His political allegiances changed over the course of the 50s BC until his tribunate, when he sided with Julius Caesar after possibly receiving a massive bribe.
During the civil war, he sided with Caesar and led Caesarian troops to Sicily and then to Africa, where he was killed in battle.
[3][4] Curio and Mark Antony had a close friendship, which was denounced by their political enemies as immoral or possibly an affair.
[6] His first recorded political activity was, with his father, to support Publius Clodius Pulcher in the senate and the courts during the Bona Dea affair.
[7] Upon his return to Rome in 52, he gave magnificent funeral games commemorating his father in collaboration with Marcus Favonius, an ally of Cato who was then serving as aedile.
[8] He also married the widow of his friend Clodius, Fulvia, who had been killed in a street battle with Titus Annius Milo that January.
However, Curio changed his views, possibly because he resented the senate's refusal to insert an intercalary month, or after receiving a massive bribe from Caesar.
The cities and communities of northern Italy quickly fell or surrendered to Caesar and he ordered the recruitment of additional soldiers.
[19][21] Curio's success in Sicily also secured its grain supply and strategic position, allowing Caesar to feed the city and gain control of the central Mediterranean.
